PPPoA Netgear dramas?

Just have a strange issue , I think I know what it is but I thought il check anyway. I live in Australia, but currently staying with my parents for a few weeks in the UK. Their landline is terrible, I mean 67dB attenuation, struggling to make a 2000kbps connection. The target SNR must be 3dB which I suspect has been lowered so BT can class it as reaching 2mbps avoiding the not spot. It holds pretty well to be fair to it, though you do notice when it drops below 2 and web pages start taking forever to load (by rights it should lose connection).

Anyway, that's just the background. I have found that for a random reason at night the router will stay in sync with the exchange, though the PPPoA connection will drop (not giving me an IP address and therefore no real internet!). I can try force it to re-connect but it doesn't have any of it and just remains lifeless until around 6.30am when it decides to come back up again. I have rebooted, hard reset, re-input log in details in this time with no success.

I would have suspected that the low SNR was making usable connection impossible and therefore the PPPoA not working etc..

However....

My own connection back in Australia is a class above , with a 8dB attenuation connecting at about 22mbps. I think there is some interference, only seem to get a 6dB SNR which *occasionally* drops un-usable (but doesn't disconnect), which is likely due to the poor installation by Telstra.

Oddly enough I have the same PPPoA drop outs, and refusal to come back up (with resets and the works not doing anything).

Both routers used are the newer Netgear models.

Is this likely to be a Netgear fault? neither router gets re-set that often so could it be in response to overtime use? or could there be another issue which I have been blind to?

Re: PPPoA Netgear dramas?

Probably 12-hour leases, but the router tries to renew it after 6 hours. So it's a rolling 12 hours.

It does that in case the renewal fails, so it gets a second chance. It sounds as though both the first and second chances are failing.

On the face of it that wouldn't explain why rebooting the router doesn't work. However if the background noise is such that there are too many errors on the line for the PPP negotiation that could explain it.

My experience of Netgears is that they are very good at holding sync, even at -1dB noise margin. I suggest next time this happens you check what it is at. A reboot at such a time, on a 67dB line, is likely to fail to sync anyway I would have thought.

Re: PPPoA Netgear dramas?

I had installed a pre-filtered faceplate previously so the ringwire and extensions were not an issue. The router had nothing to indicate any timeout or renewal going on.

the logs would only say PPP disconnect. PPP allowed to come back up, and would stay at that for a good 40mins at a time before finally connecting.

So far I think this has been solved. I called the ISP (Plusnet) and firstly requested the target SNR to go to 6 to just generally help things. For some reason the tech team thought it would be much better on a target of 9, which effectively halfed the connection speed (2400kbps~ to 1350kbps~) however a usable slower connection is a heap load better than a fast intermittent.

The PPP connection hasn't dropped yet. But then again I didn't give it long enough to test before I went out and bought a new router (Netgear again... but the fancy new D6300) The thing is pretty swish, and the chipset must like the new BT DSLAM because with snr of 9 its at least synching at ~1800kbps which may just about scrape a 1.5mbps profile?

The router has been going for a few days straight without issue.

My guess would be that the router had served its time, having being left on 24/7 for the best part of 3 years, and that it simply needed replacing.
